LOCK.

Specification of Letters Patent.

Patented April 28, 1908.

Application filed. May 14, 1906. Serial No. 316,654.

To all whom it may concern:

Be it known that I, HENRY FRANCIS KEIL, a citizen of the United Statesof America, and a resident of Bronxville, in the county of lVestchesterand State of New York, have invented a certain new and useful Lock, ofwhich the following is a specification, the same being a full, clear,and exact descrip tion of the invention, such as will enable thoseskilled in the art to which it appertains to make and use the same.

My invention relates to ap liances for securing in position doors anlike movable articles, and in particular to looks and latches adapted tobe inserted in a notch or recess in the stile of a door and having acombined escutcheons and face plate, the escutcheons, against which theknob shanks bear, having orifices larger than the knob spindle, andwhich embody certain novel features of construction and combination andarrangement of parts, of simple construction and eflicient in operation,all of which will be hereinafter described and fully illustrated in thedrawings.

To attain the desired end, this, my invention, consists in theconstruction, arrangement and operation of parts herein set forth.

In order to enable the invention to be fully understood I will proceedto explain. the

same by reference to the drawings, illustrative of one embodiment of theinvention, which accompany and form a part of this specification, and inwhich Figure 1 is a perspective View of a lock in which the invention isembodied, the lockfaoe being fixed in width Figs. 2- and 3 are sections,showing the lock partly applied to and also fastened on both sides toa'bevel edged door; Fig. 4 is a section through the knob; and Fig. 5 isa view in detail of the lock-face adjusting mechanism.

Like letters of reference indicate like parts in all the views.

Referring particularly by letter to the drawings, A, A denote mycombined escutcheon plates and face plate which rests against the sidesof a door and extends around its front edge, and overlaps the notch C,and which is preferably made of sheet metal. The combined escutcheonplates A v and face plate A is of a unitary construction, so far as itsfunction in supporting with in the same the lock case D (which containsa suitable lock or latch mechanism) and in serving as a covering for thenotch or recess is concerned, may be considered as an entirety no matterwhether it is integral and is made of a single piece of metal as shownin Fig. 1, or whether it is composed of a plurality of plates rigidlyfastened together, as

through orifices of the escutcheon plates.

The lock-case D is a complete article of itself consisting of the body dand cap d and is supported within the combined escutcheons and lock-faceby means of screws 61 inserted into the front of the lock-case throughthe face plate A The lock-case D is inserted into a recess, notch ormortise C formed in the edge of the door, preferably by simply sawing apiece out to the depth of the lock, and the top and bottom edges a, a a(or, as it were, flanges of the escutcheon plates, extensions of theface plate) being of greater dimensions or size than the opening orrecess in the door, overlap the same, and thereby entirely cover orframe in the mortise and conceal any possible poor cutting out of thedoor, in the event of the same being carelessly or hastily done. The topand bottom edges a, c also serve to afford resistance flanges or bordersor stops in order to revent any danger of the lock from being pu led outof its position to any degree, or any lateral displacement thereof, orthe bending or the straining of any of the parts, inasmuch as the saidedges a, a rest against the sides and front edge of the door, thelock-face A also serving to support the lock-case D.

' The combined escutcheons and face plate not only forms a protection tothe wood of the door, but the said structure is very readily and quicklyattached to the door by simply slipping the combined escutcheons andface plate over the edge of the door and thereby inserting the lock inthe notch or recess cut out of the stile and then screwing theescutcheons to the sides of the door in the proper applied position byoperating the screws E This invention is applicable to all kinds ofdoors to which mortise or rim locks can be attached, and is manifestlyapplicable to both locks and latches, or a combination of the twof Iprovide simple means for adapting my combined escutcheons and face plateto be used for doors of different thicknesses, which preferably consistsin making the same so as to be expansible and adjustable as regards thewidth of the face plate, as, in the present embodiment, by forming thesame with a.

plaited or folded face plate, the folds or plaits a of the sameordinarily lying between the lock-case and the heads of the screws E.The shanks of the screws E work in threaded holes in the sides of thelock-case and may be operated by a tool inserted in the orifices aformed in the extensions of the face plate, by which means theadjustability or degree of expansion of the face plate may be regulated.

In case the combined escutcheons and face plate is-applied to a thindoor,the seam be tween the folds a will be closed, but in the event ofthe structure being used in connec tion with. and attached to a thickdoor, as often occurs, thefolds a will be opened some what (the screws Ehaving been unscrewed) and after the combined escutcheons and face plateis adjusted in position, the screws E may be tightened so as to serve tohold, in connection with the escutcheon screws E, the entire structurerigidly upon the door.

In some cases I prefer to construct the combined escutcheons and faceplate of such a thickness, when formed up, as will conform to a standardthickness of a door, and to that end the escutcheons are permanentlyheld a certain distance apart by the lock-face which is fixed in widthand not expansible laterally, as shown in Fig. l.

I ordinarily construct the knob roses B so as to be carried by theescutcheons and to allow some play or movement of the knob shanksencircled by the same. The said knob roses may consist of separatepieces either loosely or rigidly attached to the escutcheons A, and theknob shanks are secured to the knob spindle b by means of screws If.

The orifices A formed in the escutcheon plates are larger than the knobspindle b, the knob roses B and knob shanks B in this embodiment beingconstructed and arranged to bear directly against the escutcheonsthrough which the knob spindle passes.

The escutcheon plates and edges or flanges thereof, together with theborders of the face plate and extensions thereof, serve to form aresistance means to the strain of pulling on the knob, and prevent theknobs, the shanks of which rest against the escutcheons, from beingpulled or forced out of the door, or any lateral displacement of thelock. Thus by pulling on one knob a resistance is afforded to theopposite shank by the escutcheon plate resting on the other sideof thedoor, which serves to resist the said strain or pull on the knob,whereby any undue pull or strain on a knob is prevented from causing.any displacement of the lock.

In case the combined escutcheon plates and face plate is to be appliedtoa" bevel edged door, I first attach one of the escutcheon plates to oneside of the door, whereupon the face plate will not register with butwill stand a little distance from the said beveled. edge, as shown inFig. 2. I then force the other escutcheon plate inwardly until theflexible lock-face registers with the said beveled edge, whereupon thelast named escutcheon plate may be screwed down to the door, as shown inFig. 7. By reason of the enlarged orifices A the lock-case D and theknob spindle b which still remain in alinement, are allowed to bedeflected slightly without in any manner impairing the operation. of thesame, as is illustrated in. Fig. 3, the said orifices being covered andconcealed by the knob roses B I provide means for actuating the lookfrom either side of a door, as a manual actuating device or thumb pieceF. Each escutcheon plate has a threaded orifice f in one of whichorifices is placed the short screw F and in the other is screwed themanual actuating device F. In applying the manual actuating device orthumb piece to the lock, the escutcheons are spread apart, and theirregularly formed and ordinarily angular and in this embodimentpreferably square bolt-actuating shank of the manual actuating device isinserted in an ordinarily angular orifice f of the. bolt actuating hubor disk of the lock mechanism, whereupon when the escutcheons resumetheir normal positions again, the thumb piece F will be undetachablyheld in working position so as to serve to. operate the latch.

The escutcheons which are preferably made of cast metal are secured. tothe extensions of the face plate by passing the lugs which are castintegrally with the said escutcheons through orifices in the face plateextension, and. then upsetting the ends thereof.

By forming the face plate and. escutcheons in separate pieces thedistance of the face plate from the knob or knob shank may be varied,and the size of the combined escutcheons and face plate thus changedhorizontally. Two strips a are cut from the top and bottom edges of eachof the folds or plaits a which strips are bent toward each other so asto lie behind the face plate and to present a practically unbroken edgeof the face plate adjacent to, and above and below, the said folds.

In this application I claim only a combined escutcheons and face placeconsisting of a flexible'face plate and rigid escutcheon plates securelyattached to the same, together with orifices in the escutcheons largerthan look spindle, the lock shanks resting against the said escutcheons,as the combined escutcheons and face plate per se, together with theother features of the invention disclosed but not claimed herein, areclaimed broadly in my applications for patent filed April 10, 1906,Serial Nos. 310,929 and 310,930.

I wish it to be understood that I do not desire to be limited to theexact details of construction shown and described, for obviousmodifications will occur to a person skilled in the art.

that I claim as my invention is:

In a look, a combined escutcheons and face plate to rest against thesides of a door and extending around its front edge and of and knobshaving shanks adapted to bear directly againstthe escutcheon plates androses supported by the knob shanks and slidable on the escutcheons.

In testimony of the foregoing specification I do hereby sign the same inthe city of New York, county and State of New York this twenty-fourthday of A ril, 1906.
